wait can I do it without a rdp? or it'll just be slower?
A rdp is alot faster than any laptop you could buy with the limited money you have and its pretty cheap at that aswell. You shouldnt be cracking from your home-pc aswell, the rdp is alot more secure.
Buy whatever laptop and then buy a rdp for cracking, for example the ones @flockbird sells. They are more powerful than any laptop you could ever buy and only cost you 10 bucks.
